DYNAMIC-MOUNTING.

Specification of Letters Patent.

Applicationfiled, May 15, 1915. Serial No. 28,306.

To all whom it may concern:

Be it known that I, WILLARD F. RICHARDS, a citizen of the United States, and a resident of Buffalo, county of Erie, and State of New York, have invented certain new and useful Improvements in Dynamo- Mountings, of which the following is a specification. I The invention relates to mountings fo dynamo electric machines, more particularly to arrangements for mounting such machines on car trucks, where the dynamo is adapted to bedriven from one of the car axles. One object of my invention is to provide a simple and efficient arrangement for this purpose, which will not interfere with other apparatus mounted beneath thecar. A further object is to provide an arrangement which is compact and in which the dynamo is easily accessible and may be removed for the purpose of inspection and repairs. A further object of the invention is to provide an arrangement in which adjustment of the dynamo supporting means toward and from the car axle, at the same time adjusts the tension on the driving belt by which the dynamo is drivenfrom the car axle. Further objects, features and advantages will more clearly appear from the detailed description given below, taken in connection with the accompanying drawings, which form apart of this specification.

In the drawings Figure 1 is a plan view, illustrating one embodlment of my invention applied on a car truck. Fig. 2 is a side view of the same. Fig. 3 is an end view of the same. Fig. 4 is a section taken on the line 44 of Fig. 1. Fig. 5is a detailed section taken on the line 55 of Fig. 1. Fig. 6 is a detailed plan view of the dynamo supporting bed structure or frame. Fig. 7 is an end view of the parts shown in Fig. 6, partly in section. Fig. 8 is a section taken on line 88 of Fig. 6. Fig. 9 is a view similar to Fig. 6, but showing a modification.

Fig. 10 is an end view of parts shown in Fig. 9, partly in section. Fig. 11 is asectionv taken on the line 11-11 of Fig. 9, also showing the generator in position. Fig. 12 is an end view of parts shown in Fig. 9.

Referring to Figs. 1 to 8, 1 represents a car truck carrying the axle 2, and car wheels 3. Rigidly bolted to side pieces of the truck on each side thereof, are bars 4, which,

-. vertical pivot bolts 14, are end pieces 15.

' are bent inwardly and downwardly, as at 5,

thence they are bent backwardly to form par allel horizontal portions -6, and thence they The two end pieces 15 are secured together by means of two rods 16, provided with cotter pins 17 in their ends. The ends of. the rods are firmly clamped to the members 15 by means ofscrew bolts 18. (See Fig. 2.)

are bent upwardly as at 7 and over the end I Carried upon the horizontal por- It will thus be seen that rods 16 and end pieces 15 form a frame or bed structure which is supported at each end on the sliding members 9, by means of the vertical pivot bolts 14. Inorder to adjust either 01 both ends of this frame or bed structure toward and away from the truck and car axle, there are provided screws 19, screw threaded into the top of the slides 9 and passing through the outer portion of the bars 5, 6 and having square heads 20 on one side of said bars and collars 21 on the other side, both rigidly secured to the screws 19, so that upon turning the screws 19, the slides 9 are adjusted inwardly and outwardly upon the horizontal portions 6 of the supporting bars. each of the supporting bars has a horizontal portion 6, and a member 5, which extends upwardly, laterally and rearwardly from the outer end of the bar, to act as a brace therefor, both ends of each bar being secured to the truck.

On the rods 16 of the bed structure, there are provided two cross members 22, lying on top of the rods 16 and two members 23, passing below the rods, 16, the members 22 and 23 being clamped together about the rod 16 by means of bolts 24.

The dynamo electric machine 25 is pro- "vided with lugs 26, having apertures there- It will be seen that through, through which apertures the rear the dynamo 25- may be made to rock about the same, so that the dynamo is prevented from sliding along the rod'16, although mounted to rotate about the rod 16 as a pivot. 27 represents a belt passing over a pulley 28 on the dynamo and a pulley 29 on the car axle, so that the dynamois driven from the car axle. It'will be noted that the center of gravity of the dynamo lies Well in front of the axes of rod 16 about which it is pivoted, so thatthe weight of the dynamo tends to keep the belt 27 taut. In order toapply additional tension to the belt, each of the members 22 is provided with outwardly extending cup portions 30 and links 31, have one end thereof pivotally secured to the dynamo, as at 32, the other end of the links passing centrally through the cupportions .30 and having screw threaded thereon, on their outerends, cups 33, coil springs 34 (see Fig. 5) being compressed between the cups 33 and 30, in such a manner'that the springs tend to pull the dynamo 25 outwardly and downwardly about its pivot rod 16 and so increase the tension on the belt 27.

By adjusting the slides 9 toward and from the car axle by means of screws 19,

its pivot rod 16, as this rod moves toward and away from-the car axle, thus decreasing or increasing the compression of the springs 34, so that the tension on the belt may be regulated in this manner. That is, if the 'cups 33 have been once adjusted to place the springs under proper tension, the tension to be applied to thebelt may be regulated by operating the screws 19, and without further adjustment of the screw cups 33.

It will be noted that the member 12 is provided with cutaway portions at 40 to accommodate the rods 16, and that as the bed structure, comprising rods 16 and end pieces 15, is movedabout pivot bolts 14, the rods 16 move in the cutaway portions 40 of the member 12. The members 12, however,

are so cut away at 40 as to provide portions which underlie the rods 16 and act as safety carriers for the rods 16, and prevent the rods 16 from vibrating, due to looseness or wear of the pivot bolts 14.

In removing or replacing the belt, it is not necessary to move both the adjustment screws 19, but only the adjustmentscrew at the belt end of the supporting structure. By moving this end of the supporting frame rearwardly, the belt may be quickly slipped off, and replaced. If the dynamo is not in alinement, either of the screws 19 may be turned slightly, so that the dynamo and its supporting bed structure will be'brought into alinement and the belt run true on the pulleys.

Referring to the modification shown in Figs. 9 to 12, inclusive, the general construction is substantially the same. However, instead of providing-the rods 16, angle naaaeee 46, enveloped by portions 47, integral with,

the end pieces 43, the ears 46 being adaptedto oscillatenback and forth in the portions 47, as the screws 19 are operated to adjust one or the otherof the ends of the supporting bed structure (comprising irons 42 and end pieces 43) along the bar 6, toward and away from the car axle. Intermediate the pivot bolts 45 there is secured to the angle irons 42, two' cross members 48, which are bolted to each of the angle irons 42 by means of bolts 49. At one end, each of the members 48' is constructed to receive one end of a rod 50, which is clamped to the inner ends of the members 48, by means of clamping bolts 51. The generator 25, as before, is provided with lugs perforated to receive the rod 50, so that the generator is pivotally mounted upon said rod, in the same manner that it was pivotally mounted in one of the rods 16 in the modification shown in Figs. 1 to 8 inclusive. The lugs 26 on the generator abut closely the ends of the members 48, so that the generator is prevented from'moving laterally along the rod 50. The members 48 are provided with forward extensions, having cups 30, as shown in connection with the modification illustrated in Figs. 1 to 9 inclusive. Links 31 are also adapted to pass through the cups 3( and have screwed on their outer ends, screw cups 33, for inclosing tension springs to apply the proper tension to the generator driving belt. Oil or grease cups may be provided wherever desired. @ne is shown at 60 (Fig. 10), for the purpose of applying lubricant to the bar 6, beneath the slides 9, and to the screws 19.

Although I have described my improvements in great detail and with respect to preferred forms thereof, nevertheless, ll do not desireto be limited to the details shown and described, as many changes and modifications may well be made without departing from the spirit and scope of my invention in its broader aspect.
